基于tomcat7 web开发中的一点小东西
控制台:
org.apache.jasper.compiler.TldLocationsCache tldScanJar
信息: At least one JAR was scanned for
TLDs yet contained no TLDs. Enable debug logging for this logger for a
complete list of JARs that were scanned but no TLDs were found in them.
Skipping unneeded JARs during scanning can
improve startup time and JSP compilation time.
这样的问题是你的页面中含有<!---->的注释 去掉就好了,tomcat7.0.20.
tomcat 7对EL表达式的语法要求比较严格,例如"${owner.new}"因包含关键字new就会导致解析出错。
问题是出来了,怎么解决呢?有三种,如下:
第一种:严格遵守java规范,修改对象的属性名称,要求不包含java关键字;
第二种:修改EL表达式,例如"${owner.new}"可以修改为"${owner['new']}";
第三种:修改tomcat属性,忽略对EL表达式的关键字检查。修改$CATALINA_BASE/conf/catalina.properties文件,添加org.apache.el.parser.SKIP_IDENTIFIER_CHECK=true选项。
